'ROBERT HILPRECHT, OF LANSING, MICHIGAN, ASSIGNOIt TO OLDS GAS POWER COMPANY, OF LANSING, MICHIGAN, A CORPORATION OF MICHIGAN.

GRATE FOR GAS-PRODUCERS.

Specification of Letters Patent.

Patented April 21, 1908.

To all 'whom 'it may concerm.-

Be it known that I, ROBERT HILPREGHT, a subject of the Emperor of Germany, residin at Lansing, in the county of Ingham and State of Michigan, have invented certain new and useful Improvements in Grates for Gas-Producers, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to gas producers of the suction type, and consists in certain features of construction as hereinafter set forth.

In the drawings, Figure 1 is a vertical central section through the producer; Fig. 2 is a plan view of the grate; Fig. 3 is a perspective vienr of a portion of the grate; and Fi. 4 is n elevation of the grate at right angles to ig. 1. l

In the operation of suction gas producers, in which American anthracite coal is employed difliculty has been experienced in reeping the. grates clear. Furthermore a grate area only equal to the cross section of the fuel support thereon has been found nsufficient to roduce satisfactory results. With these di, culties in View, the present invention consists primarily in the novel construction of the grate, andfurther in the peculiar construction and arrangement ofv said grate in relation to the other portions of the producer.

A is the producer casing, preferably of cylindrical form, having a vertically arran ed axis; B is the hearth at the lower end of t is casing, and F is the lining of refractory material.

The chamber within the producer is preferably cylindrical in form, and substantially uniform in diameter from top to bottom.

'lhe fuel in this chamber is supported by a grate, but, to provide a greater open area, this grate is of a basket form. Thus the air has access to the fuel through the conical sides, as well as the bottom of the grate, preventing the formation of clinker and the putting out of the 'lire at any point due to the chilling effect of the vapor Vmixed with' the air.

In detail construction, this basket grate com rises a series of separate sections, referab y individually separable bars G, W 'ch are arranged around the casing adjacent to each other to form the basket. are su ported at their uppler provi ed with hooksjI-I,

These bars ends by being ch engage bear ings upon an annular shelf or plate I, upon which the refractory lining F is sup orted. The bearing for the hooks H is formed by an annular ange J de ending and extending outward from the p ate I. At their lower ends the bars G are held together yby a surrounding ring K, preferab y an inturned flange on an annular member L, which enages outwardly of the hooks M on the bars The member L also forms a support for a flat grate N slidably engaging Ways O.

The individual grate bars G are s aced from each other by laterally projecting ugs P near their upper ends, and referably also rounded bosses Q adjacent to tfieir lower ends. Thus, when engaged with the rings J and K, the bails will be uniformly spaced from each ot er.

With the construction described, the grate may be readily assembled, or taken down for repairs, it being only necessary to slightly elevate the lower ring L, which will permit sufficient lateral movement of the hooks H to disengage them from or engage them with the annular fiange J. .In operation, the spaces between the bars and in the flat slidable grate N will provide abundant access to the air and vapor, and Whenever the grate becomes clogged with ashes, it may be shaken by sliding the entire series of bars upon the annular flange J.

' What I claim as my invention is:

l. In a gas reducer, the combination with a casing, o an annular bearing therein, a series of grate sections having a hooked engagement with -said annular bearing, a rin carried by and surrounding the lower en s of said grate sections to hold them together, and a flat grate supported by said ring.

2. In a gas reducer, the combination with a casing and a refractory lining therein, of an annular plate sup orting said refractory lining and provide with -a depending annular bearing, a series of grate sections having hooked engagement with said annular bearing, a ring carried by said grate sections for holding said grate sections together at their lower` ends, and a flat grate supported by said ring.

3. In a gas producer, the combination with a casing, of a refractory lining therefor, an annular plate supporting said lining, an annular bearing depending from said plate, a series of gratebars having reversely bent 10 said annular bearing, an

hooks at their opposite ends, the upper hools .being 'engaged .with said annular bearing,

spacing means between said grate bars and an annular member carried by the lower hooks, and holding said bars together.

4. In a gas roduoer, the combination with `a casing, oi 'an Vannular bearing within said easing, a series of longitudinally S-shaped grate bars having their u per ends engaging an annular meinberloarried by'and engagin V'the lower endsI ROBERT HILPRECHT. Witnesses S. J. SMG-ER, N. T. HARRINGTON.
